Synthesis and Characterization of Donor-Acceptor Copolymers Having Dithienophene – Benzothiadiazol Moieties Suitable for Use in Solar Cells
Abstract
Since the discovery of conducting polymers, researches have been focused on the design and synthesis of new type polymers for development of novel conductive materials. Wynberg et al. have discovered donor-acceptor copolymers and this event has received a great deal of interest. The most important feature of these copolymers is that the band gaps are lowered because of the delocalization of π electrons over electron-donating and electron-accepting groups. For this purpose, several donor and acceptor groups were introduced and they have been concluded to be suitable for light emitting diodes (LEDs) and solar cells. Dithienothiophenes, comprising three fused thiophene rings, have a quite rich electronic structure and therefore, they are expected to show a donor-type behavior. Recently, better donor-type groups were discovered when compared to the ones in the past and their properties were investigated in terms of usability in solar cell applications. In this study, we have synthesized and characterized DTT-Btz-containing donor-acceptor copolymers.
